Osaka Kaunei Girls’ Academy captured its first national title at the 78th National High School Basketball Championship Winter Cup 2025 on Day 6 at Tokyo Gymnasium, led by 160-centimeter sophomore Rion Matsumoto, who scored 8 points and earned a spot on the tournament’s Best 5. Leaving her hometown to pursue basketball in Osaka two years ago, she thanked her family, especially father Toshiya, for the support that helped make the victory possible. In the final against Sakura Gakuen of Aichi, Osaka overturned a first-half deficit to clinch the title as Matsumoto logged significant minutes (37:07). After the victory, she vowed to win back-to-back titles next year.
